Business Report

I. The 2025 Business Report:

(I) Implementation results of the business plan

The consolidated operating income of 2025 is NTD 804,878 thousand; The Company's API, Rapamycin, can not only be used as the API for immunosuppressants, but also the intermediate for Everolimus and the drug coating for cardiovascular stents. The Company has worked with major international medical device manufacturers for many years. Several of its customers have entered late-stage clinical trials and are preparing to launch their cardiovascular stents. Future demand is anticipated. At present, the increase in Rapamycin sales is mainly due to medical device customers building up inventory in preparation for launch.

Everolimus, an immunosuppressant and anti-cancer drug, was approved by the FDA through the Company's U.S. customer in June 2020, granting 180-day market exclusivity. In 2021, besides the existing low-dose generic drug Afinitor (2.5 mg, 5.0 mg, and 7.5 mg), the customer also marketed the high-dose (10 mg) product in 2021. Due to the launch of several U.S. clients' preparations made with the Company's API, Everolimus, the demand from these customers increased tremendously. The Company has been active in producing its own intermediates while at the same time seeking other raw material suppliers in order to continuously fulfill U.S. clients' demand and improve its market share. This product has become the major force driving the revenue and profit growth in recent years.

In response to European clients' optimistic view about the market growth of the anti-fungal infection product Caspofungin, the Company increased the capacity of existing production lines to lower cost. Provides customers with more competitive APIs to enhance their market competitiveness. Backed with both enlarged capacity and competitive price in addition to a triple-digit growth of customer demand in this year, ongoing growth momentum is anticipated in the future.

The Company is also engaged in the manufacture of the immunosuppressive drug Tacrolimus. With the continued expansion of the fermentation production line and increased production investment, coupled with competitive advantages in production capacity and price, continuous cultivation of the Japanese market has driven increased Tacrolimus orders from customers, which is expected to result in significant revenue growth for the Company.

Triglyceride - fish oil active pharmaceutical ingredient ethyl icosapentate

(EPAE). In 2024, the annual production capacity of the product was further increased and the unit cost was reduced through the continuous optimization of the EPAE process and the introduction of a continuous process (MCFE). The increase in production capacity has been sufficient to meet customer market demand, and customers have also accumulated a significant amount of inventory. As a result, overall demand has slowed this year.

The Company underwent a factory inspection by the TFDA and 16 customer audits in 2025, and passed all of them. The customers that performed the audit were from the U.S., Europe, Japan, India, and other countries. Our Company, nevertheless, still adheres to the cGMP implementation and manufacturing specifications by strictly implementing the cGMP system operation as officially accredited by and consistent with the requirements of the United States, European Union (EU) and Japan. Our implementation under such policy will be helpful to the Company to continually develop the global markets dominated in Europe, the United States and Japan.

Appendix III

Auditor's Report

(2026) Cai-Shen-Bao-Zi No. 25004038

To Chunghwa Chemical Synthesis & Biotech Co., Ltd.,

Audit opinion

We have audited the accompanying proprietary consolidated balance sheet of Chunghwa Chemical Synthesis & Biotech Co., Ltd. and its subsidiaries (hereinafter referred to as Chunghwa Group) as of December 31, 2025 and 2024 and the related consolidated statements of income, of changes in shareholders' equity and of cash flows and Notes to consolidated financial statement (including significant accounting policies) for the years then ended.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Chunghwa Group as of December 31, 2025 and 2024, and the results of its operations and its cash flows for the years then ended in conformity with the "Regulations Governing the Preparation of Financial Reports by Securities Issuers," and International Financial Reporting Standards (IFRS) that was approved and announced effective by the Financial Supervisory Commission, International Accounting Standards, Interpretations, and Notices (IFRS), International Accounting Standards (IAS), Interpretation (IFRIC) and Interpretative Announcement (SIC).

Basis of an audit opinion

We conducted our audit of the financial statements in accordance with the Regulations Governing Auditing and Attestation of Financial Statements by Certified Public Accountants and Auditing Standards. The responsibilities of the independent auditor under these standards will be further explained in the paragraph of "independent auditor's responsibility for consolidated financial statements." The personnel of the CPA Firm subject to the independence requirement have acted independently from the business operations of Chunghwa Group in accordance with the Code of Ethics and with other responsibilities of the Code of Ethics performed. We believe that our audit provides a reasonable basis for our opinion.

Key Audit Matters

The "key audit matters" means that the independent auditor has used their professional judgment to audit the most important matters on the 2025 consolidated financial statements of Chunghwa Group. The key audit matters have been responded to in the process of auditing the consolidated financial statements as a whole and forming an audit opinion; therefore, the independent auditor does not express an opinion on these matters separately.

The key audit items from the 2025 consolidated financial statement of Chunghwa Chemical Synthesis and Biotech Co., Ltd. are presented below:

Accounting assessment of inventory valuation

Description of the matter

See Note 4 (12) in the consolidated financial report regarding the accounting policy on inventory valuation, Note 5 (2) for the accounting assessment and hypothetical uncertainty on inventory valuation, and Note 6 (4) for the description of the inventory account.

Chunghwa Group is engaged mainly in the production and sale of active pharmaceutical ingredients. Since active pharmaceutical ingredients are in a severely competitive market and sensitive to shelf life, the risk of losses from inventory devaluation or obsolescence is higher. Since the inventories involve large amounts of money and large numbers of items that require laborious work by human beings to identify expired or damaged goods, we regard the assessment of allowance to reduce inventory to market as a key audit item.

The responsive auditing process

Our key audit procedures performed in respect of the above area included the following:

Assessing the reasonableness of policy on allowance to reduce inventory to market in accordance with our understanding of the Company's operations and the nature of the business.
Performing sampling tests to examine if the market price of net realized value is consistent with the Company's policy, and randomly examining the accuracy of the selling price of individual inventory parts and the way net realized value is calculated.
Obtain out-of-date inventory details that are identified by the management, check the related information and verify the account records.

Checking whether the time point of sales income recognition is appropriate

Description of the matter

For the accounting policy on the recognition of income, please refer to Note 4 (26) of the consolidated financial statement. For information on income accounts, please refer to Note 6 (16) of the consolidated financial statement. As stated in the accounting policies, the sales revenue is recognized when products are delivered to customers who have discretionary power in channels and prices of products sold and Chunghwa Chemical Synthesis and Biotech has no outstanding performance obligations which may affect customers' acceptance of products. As exports are the main source of income for Chunghwa Chemical Synthesis & Biotech Co., Ltd., the terms of business agreed upon between the Company and its customers are the basis of income assessment. However, such a process often involves a lot of manpower for verification and may lead to inappropriate income recognition time points. Therefore, we regard the sales income recognition time points as a key audit item.

The responsive auditing process

13 -

Our key audit procedures performed in respect of the above area included the following:

Understand and evaluate the Group’s operating process and internal controls at the cut-off points of the revenue recognition to assess the effectiveness of management’s control over sales revenue recognition.
The execution of sales and income over a certain period before and after the time periods covered in the financial report were examined with the packing lists, customer orders and declaration forms in order to confirm that income was recognized at appropriate periods.

Other matters - individual financial report

Chunghwa Group has compiled its 2025 and 2024 individual financial statements, for which we issued unqualified opinion.

The responsibility of the management and management units to the consolidated financial statements

The responsibility of the management is to have the consolidated financial statements presented fairly, in all material respects, in accordance with the “Regulations Governing the Preparation of Financial Reports by Securities Issuers”, and International Financial Reporting Standards (IFRS) that was approved and announced effective by the Financial Supervisory Commission, International Accounting Standards, Interpretations, and Notices (IFRS), International Accounting Standards (IAS), Interpretation (IFRIC) and Interpretative Announcement (SIC); also, maintain the necessary internal controls related to the consolidated financial statements in order to ensure that the consolidated financial statements are free of any material misstatement arising from fraud or errors.

While preparing the consolidated financial statements, the management’s responsibility also includes assessing the continuing operation of Chunghwa Group, the disclosure of the relevant matters, and the adoption of the accounting base for continuing operation, unless the management intends to liquidate Chunghwa Group or cease the business operation, or there is lack of any alternative except for liquidation or suspension.

The governance units (including the Audit Committee) of Chunghwa Group are responsible for supervising the financial reporting process.

The responsibilities of the independent auditor to the consolidated financial statements

The purpose of the independent auditor’s auditing the consolidated financial statements is to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement arising from fraud or errors and with an audit report issued. Reasonable assurance means a high degree of assurance. However, the audit conducted in accordance with auditing standards of the R.O.C. does not guarantee having any material misstatement in the consolidated financial statements detected. Material misstatement could arise from fraud or errors. If the misstated amount or aggregated amount is reasonably expected to affect the economic decisions made by the

14 -

users of the consolidated financial statements, it is considered significant.

We used professional judgment and suspicion during the audit in accordance with the auditing standards of the Republic of China. The independent auditor also performs the following tasks:

Identify and evaluate the risk of material misstatement arising from fraud or errors of the consolidated financial statements; design and implement proper responsive measures to the risk assessed; also, obtain sufficient and adequate audit evidences for forming an audit opinion. The risk of fraud may involve conspiracy, forgery, deliberate omission, false declaration, or violating internal control; therefore, the risk of material misstatement arising from the undetected fraud is higher than that caused by errors.
Obtain necessary understanding on the internal control related to the audit in order to design appropriate audit procedures under the circumstance, but the purpose is not to express an opinion on the effectiveness of the internal control of Chunghwa Group.
Assess the appropriateness of the accounting policies adopted by the management; also, the reasonableness of the accounting estimates and related disclosures made.
Base on the audit evidence obtained to make conclusions on the suitability of the accounting base for continuing operation base adopted by the management and whether or not the events or circumstances causing significant doubts to the continuing operation ability of Chunghwa Group are with significant uncertainties. If the independent auditor believes that such events or circumstances are with significant uncertainties, it is necessary to remind the users of the consolidated financial statements in the audit report to pay attention to the relevant disclosure or to revise the audit opinion when such disclosures are inappropriate. The conclusion of the independent auditor is based on the audit evidence obtained as of the audit report date. However, future events or circumstances may result in the inability of Chunghwa Group to continue operating.
Assess the overall expression, structure, and content of the consolidated financial statements (including the relevant notes) and whether or not the relevant transactions and events in the consolidated financial statements are presented fairly.
Obtain sufficient and appropriate audit evidence on the financial information of business entities within the Group in order to express an opinion on the consolidated financial statements. The independent auditor is responsible for guiding, supervising, and implementing the audit of the Group; also, is responsible for forming an opinion on the audit of the Group.

The matters communicated by the independent auditor to the governing unit include the scope and timing of the planned audit, and the significant findings (including the major nonconformities of internal controls identified in the auditing process).

The independent auditor has provided the declaration of independence of the CPA Firm personnel subject to the Code of Ethics to the governing unit; also, it has communicated with the governing unit regarding the relationship and other matters (including the relevant protection measures) that may affect the independence of the independent auditor.

15 -

The independent auditor has based on the communications with the governing unit to determine the key audit matters to be performed on the 2025 consolidated financial statements of Chunghwa Group. The independent auditor shall state the key audit matters in the audit report except for the specific matters prohibited by law from being disclosed, or, in rare cases; the independent auditor decides not to have specific matters communicated in the audit report since the negative effect of such disclosure can be reasonably expected to be greater than the increase of public interest.

Auditor's Report

(2026) Cai-Shen-Bao-Zi No. 25003653

To Chunghwa Chemical Synthesis & Biotech Co., Ltd.,

Audit opinion

We have audited the accompanying proprietary individual balance sheet of Chunghwa Chemical Synthesis & Biotech Co., Ltd. as of December 31, 2025 and 2024 and the related individual statements of income, of changes in shareholders' equity and of cash flows and Notes to individual financial statement (including significant accounting policies) for the years then ended.

In our opinion, the individual financial statements referred to above present fairly, in all material respects, the financial position of Chunghwa Chemical Synthesis & Biotech Co., Ltd. as of December 31, 2025 and 2024, and the results of its operations and its cash flows for the years then ended in conformity with the "Regulations Governing the Preparation of Financial Reports by Securities Issuers".

Basis of an audit opinion

We conducted our audit of the financial statements in accordance with the Regulations Governing Auditing and Attestation of Financial Statements by Certified Public Accountants and Auditing Standards. Our responsibilities under those standards are further described in the responsibilities of auditors for the audit of the separate financial statements. The personnel of the CPA Firm subject to the independence requirement have acted independently from the business operations of Chunghwa Chemical Synthesis & Biotech Co., Ltd. in accordance with the Code of Ethics and with other responsibilities of the Code of Ethics performed. We believe that our audit provides a reasonable basis for our opinion.

Key Audit Matters

The "key audit matters" means that the independent auditor has used their professional judgment to audit the most important matters on the 2025 individual financial statements of Chunghwa Chemical Synthesis & Biotech Co., Ltd.. The key audit matters have been responded to in the process of auditing the individual financial statements as a whole with an audit opinion formed; therefore, the independent auditor does not express an opinion on these matters separately.

24 -

The key audit items of the 2025 individual financial report of Chunghwa Chemical Synthesis & Biotech Co., Ltd. are presented below:

Accounting assessment of inventory valuation

Description of the matter

See Note 4 (11) in the individual financial report for details about the accounting policy on inventory valuation, Note 5 (2) for accounting assessment of inventory valuation and hypothetical uncertainty, and Note 6 (4) for an inventory account description.

Chunghwa Chemical Synthesis & Biotech Ltd. is engaged mainly in the production and sale of active pharmaceutical ingredients. Since active pharmaceutical ingredients are in a severely competitive market and sensitive to shelf life, the risk of losses from inventory devaluation or obsolescence is higher. Since the inventories involve large amounts of money and large numbers of items that require laborious work by human beings to identify expired or damaged goods, we regard the assessment of allowance to reduce inventory to market as a key audit item.

The responsive auditing process

The corresponding auditing procedures are as follows:

Assessing the reasonableness of policy on allowance to reduce inventory to market in accordance with our understanding of the Company's operations and the nature of the business.
Conduct sampling tests to see if the basis for market prices of net realized value is consistent with the Company's policy. Randomly check the correctness of the selling prices of individual inventory parts and the way net realized value is calculated.
Obtain out-of-date inventory details that are identified by the management, check the related information and verify the account records.

Checking whether the time point of sales income recognition is appropriate

Description of the matter

For the accounting policy on the recognition of income, please refer to Note 4 (25) of the individual financial statement. For information on income accounts, please refer to Note 6 (16) of the individual financial statement. As stated in the accounting policies, the sales revenue is recognized when products are delivered to customers who have discretionary power in channels and prices of products sold and Chunghwa Chemical Synthesis and Biotech has no outstanding

25 -

performance obligations which may affect customers' acceptance of products. As exports are the main source of income for Chunghwa Chemical Synthesis & Biotech Co., Ltd., the terms of business agreed upon between the Company and its customers are the basis of income assessment. However, such a process often involves a lot of manpower for verification and may lead to inappropriate income recognition time points. Therefore, we regard the sales income recognition time points as a key audit item.

The responsive auditing process

The corresponding auditing procedures are as follows:

Understand and evaluate the Company's operating process and internal controls at the cut-off points of the revenue recognition to assess the effectiveness of management's control over sales revenue recognition.
The execution of sales and income over a certain period before and after the time periods covered in the financial report were examined with the packing lists, customer orders and declaration forms in order to confirm that income was recognized at appropriate periods.

The responsibility of the management and management units to the individual financial statements

The management team is responsible for preparing individual financial statements in accordance with the "Regulations Governing the Preparation of Financial Reports by Securities Issuers" to present the Company's financial status in an objective way and for necessary internal controls, ensuring that the statements do not contain any false content due to fraudulence or mistakes.

While preparing the individual financial statements, the management's responsibility also includes assessing the continuing operation of Chunghwa Chemical Synthesis & Biotech Co., Ltd., the disclosure of the relevant matters, and the adoption of the accounting base for continuing operations, unless the management intends to liquidate Chunghwa Chemical Synthesis & Biotech Co., Ltd. or cease business operation, or there is lack of any alternative except for liquidation or suspension.

The governance units (including the Audit Committee) of Chunghwa Chemical Synthesis & Biotech Co., Ltd. are responsible for supervising the financial reporting process.

The responsibilities of the independent auditor to the individual financial statements

The purpose of the independent auditor's auditing of the individual financial statements is

26 -

to obtain reasonable assurance about whether the individual financial statements are free of material misstatement arising from fraud or errors and with an audit report issued. Reasonable assurance means a high degree of assurance. However, the audit conducted in accordance with auditing standards of the R.O.C. does not guarantee having any material misstatement in the individual financial statements detected. Material misstatement could arise from fraud or errors. If the misstated amount or aggregated amount is reasonably expected to affect the economic decisions made by the users of the individual financial statements, it is considered significant.

We used professional judgment and suspicion during the audit in accordance with the auditing standards of the Republic of China. The independent auditor also performs the following tasks:

Identify and evaluate the risk of material misstatement arising from fraud or errors of the individual financial statements; design and implement proper responsive measures to the risk assessed; also, obtain sufficient and adequate audit evidences for forming an audit opinion. The risk of fraud may involve conspiracy, forgery, deliberate omission, false declaration, or violating internal control; therefore, the risk of material misstatement arising from the undetected fraud is higher than that caused by errors.
Obtain necessary understanding on the internal control related to the audit in order to design appropriate audit procedures under the circumstance, but the purpose is not to express an opinion on the effectiveness of the internal control of Chunghwa Chemical Synthesis & Biotech Co., Ltd..
Assess the appropriateness of the accounting policies adopted by the management; also, the reasonableness of the accounting estimates and related disclosures made.
Base on the audit evidence obtained to make conclusions on the suitability of the accounting base for continuing operation base adopted by the management and whether or not the events or circumstances causing significant doubts to the continuing operation ability of Chunghwa Chemical Synthesis & Biotech Co., Ltd. are with significant uncertainties. If the independent auditor believes that such events or circumstances have significant uncertainties, it is necessary to remind the users of the individual financial statements in the audit report to pay attention to the relevant disclosure or to revise the audit opinion when such disclosures are inappropriate. The conclusion of the independent auditor is based on the audit evidence obtained as of the audit report date. However, future events or circumstances may result in the inability of Chunghwa Chemical Synthesis & Biotech Co., Ltd. to continue operating.
Assess the overall expression, structure, and content of the individual financial statements (including the relevant notes) and whether or not the relevant transactions and events in the individual financial statements are presented fairly.
Obtain sufficient and appropriate audit evidence on the financial information of business entities within the Group in order to express an opinion on the individual financial statements. The independent auditor is responsible for guiding, supervising, and
27 -

implementing the audit of the business entity; also, it is responsible for forming an opinion on the audit of the individual financial statements.

The independent auditor has based on the communications with the governing unit to determine the key audit matters to be performed on the 2025 individual financial statements of Chunghwa Chemical Synthesis & Biotech Co., Ltd.. The independent auditor shall state the key audit matters in the audit report except for the specific matters prohibited by law from being disclosed, or, in rare cases; the independent auditor decides not to have specific matters communicated in the audit report since the negative effect of such disclosure can be reasonably expected to be greater than the increase of public interest.

Appendix VI

Chunghwa Chemical Synthesis & Biotech Co., Ltd.

Information on Intended Private Placement for Issuance of Common Stock Shares or Domestic Convertible Corporate Bonds (Including Secured or Unsecured Convertible Corporate Bonds):

I. To enrich the operating capital, pay off debts borne by the Company, or for other demands for funds to support future developments of the Company, the Company intends to introduce strategic funds raised by investors through private placement reflective of the market situation and the needs of the Company for issuance either common stock shares or domestic convertible corporate bonds (including secured or unsecured convertible corporate bonds) or common stock shares in combination with domestic convertible corporate bonds separately or concurrently. The actual number of shares to be issued or convertible is to be decided by the Board of Directors as authorized through the shareholders' meeting depending on the situation on the capital market and may not exceed 20% (that is, 15,383,600 shares) of the total number of outstanding shares.

II. Clarifications are provided below as required by Article 43-6 Paragraph 6 of the Securities and Exchange Act:

(I) Basis for and legitimacy of pricing:

The price per share of private placement common stock may not be below 80% of the reference price. The reference price is the higher of those calculated according to the two criteria below:

(1) The price obtained with the simple arithmetic mean of the closing prices of the one, three, or five business days prior to the pricing date from which the free allotment ex-right and cash dividend subtracted and capital decrease reverse ex-right added back up.

(2) The price obtained with the simple arithmetic mean of the closing prices of the thirty business days prior to the pricing date from which the free allotment ex-right and cash dividend subtracted and capital decrease reverse ex-right added back up.

Private convertible corporate bonds:

(1) Denomination: NTD 100,000 or its multiples.

(2) Issuance period: not more than seven years from the issuance date.

(3) Coupon interest rate: tentatively set at 0% annual interest rate.

(4) The issue price of private placement convertible corporate bonds may not be below 80% of the theoretical price. The theoretical price will be determined with the valuation model selected that covers and takes into consideration at the same time various rights included in the issuance criteria. The conversion price was determined by calculating the simple arithmetic average of the closing price of the common stock for one,

36 -

three or five business days prior to the price determination date, less the ex-rights and dividends of stock dividends, and adding back the anti-ex-rights of the capital reduction, or the simple arithmetic average of the closing price of the common stock for 30 business days prior to the price determination date, less the ex-rights and dividends of stock dividends, and adding back the anti-ex-rights of the capital reduction. It shall be the higher of the two calculations and the price shall not be less than 80% of the reference price.

Within the scope while the price on the substantial pricing date and substantial private placement price (including the conversion price of the private placement convertible corporate bonds) are not below the range as resolved in the shareholders' meeting, it is proposed that the shareholders' meeting should authorize the Board of Directors to solicit specific people as the market update may justify. The private placement price (including the conversion price of private placement convertible corporate bonds) is determined according to the laws and regulations set by the competent authority, with reference to the reference price or theoretical price mentioned above in addition to the "three-year transfer restriction" for private placement securities under the Securities and Exchange Act; as such, the price set shall be reasonable.

(II) Choice of specific persons: Specific persons are limited to strategic investors meeting the eligibility criteria specified under Article 43-6 Paragraph 1 of the Securities and Exchange Act, capable of helping the Company improve its technologies, quality, bring down the cost, boost efficiency, maximize market share, enhance corporate governance, and strengthen risk management, and approving the management philosophy of the Company. Approaching strategic investors meeting the foregoing criteria is meant to meet, required for, and expected to render benefits in terms of the Company's long-term development needs. It is intended to help the Company fulfill the foregoing benefits taking advantage of the experience, knowledge, technical background, distribution channels, or deployment of the said strategic investors. No specific persons have been approached by the Company so far. It is intended to authorize the Board of Directors through the shareholders' meeting to take care of approaching specific persons.

(III) Rationale for organizing private placements:

Why no public offering? In light of the situation on the capital market, time-efficiency, feasibility, and issue cost of capital raising, and the actual needs for introducing strategic investors, the requirement that private placement securities may not be transferred freely within three years helps ensure the long-term partnership between the Company and its strategic investors; as such, securities are issued not through public offering but through private placement.
Private placement limit: Not to exceed 15,383,600 common stock shares.
The purpose of using the funds acquired through private placement and the
37 -

benefits anticipated therefrom: The Company will carry out the private placement task either once or in batches (not beyond three times in maximum) dependent upon the market update and the fact of the specific people. The funds so acquired through private placement either once or in batches are anticipated to be used to enrich the working capital, pay off the Company's debts or to satisfy other needs aiming at the Company's future development. Each private placement is expected to reinforce the competitive advantages of the Company, improve the operating efficacy, and strengthen the financial structure and hence helps with the shareholders' equity positively.

III. Major details of the current plan to issue common stock shares or domestic convertible corporate bonds (including secured or unsecured convertible corporate bonds) through private placement include the actual issue price, number of shares, issuance criteria, value of private placement, capital increase base date, action items, expected progress, and expected possible benefits, among others, as well as all the other matters and mechanisms concerning the issuance plan are intended to be placed at the discretion of the Board of Directors as authorized through the shareholders' meeting, too. The Board of Directors may adjust, define, and manage them reflective of the situation on the market and may also revise or change them as instructed by the competent authority or based on the operational evaluation or in response to the objective environment as needed.

IV. The rights and obligations associated with the current private placement common stock shares are identical to those of outstanding common stock shares of the Company. Applicable restrictions for securities in the current private placement shall be based on Article 43-8 of the Securities and Exchange Act and clarifying letters of applicable laws and regulations from the competent authority.

V. To facilitate the current placement of securities, it is intended to authorize the Chairman or his/her designee through the shareholders' meeting to negotiate, finalize, and enter into all contracts and documents concerning the current private placement and take care of all the matters required for the current private placement on behalf of the Company. For matters not specified above, the Chairman is authorized to handle them at his/her own discretion as required by law.

48 -

To convene a virtual-only shareholders meeting, appropriate alternative measures available to shareholders with difficulties in attending a virtual shareholders meeting online shall be specified.

Article 7: If a shareholders meeting is convened by the board of directors, the meeting shall be chaired by the chairperson of the board. When the chairperson of the board is on leave or for any reason unable to exercise the powers of the chairperson, the vice chairperson shall act in place of the chairperson; if there is no vice chairperson or the vice chairperson also is on leave or for any reason unable to exercise the powers of the vice chairperson, the chairperson shall appoint one of the managing directors to act as chair, or, if there are no managing directors, one of the directors shall be appointed to act as chair. Where the chairperson does not make such a designation, the managing directors or the directors shall select from among themselves one person to serve as chair.

When a managing director or a director serves as chair, as referred to in the preceding paragraph, the managing director or director shall be one who has held that position for six months or more and who understands the financial and business conditions of the company. The same shall be true for a representative of a juristic person director that serves as chair.

A shareholders' meeting convened by the board of directors shall be chaired by the chairman in person and shall be attended by a majority of the total director seats in the Board and shall be attended by the minimum of one independent director while each functional committee shall have at least one representative to participate in the meeting. The facts of participation shall be expressly recorded into the minutes of the shareholders' meeting.

If the shareholders' meeting is convened by any authorized party other than the Board of Directors, the convener will act as the meeting chairman. If there are two or more conveners, they shall appoint one among themselves to chair the meeting.

The Company may appoint its attorneys, certified public accountants, or related persons retained by it to attend a shareholders' meeting in a non-voting capacity.

Article 8: The Company, beginning from the time it accepts shareholder attendance registrations, shall make an uninterrupted audio and video recording of the registration procedure, the proceedings of the shareholders meeting, and the voting and vote counting procedures.

The recorded materials of the preceding paragraph shall be retained for at least one year. If, however, a shareholder files a lawsuit pursuant to Article 189 of the Company Act, the ballots shall be retained until the conclusion of the litigation.

Where a shareholders meeting is held online, the Company shall keep records of shareholder registration, sign-in, check-in, questions raised, votes cast and results of votes counted by the Company, and continuously audio and video record, without interruption, the proceedings of the virtual

49 -

meeting from beginning to end.

The information and audio and video recording in the preceding paragraph shall be properly kept by the Company during the entirety of its existence, and copies of the audio and video recording shall be provided to and kept by the party appointed to handle matters of the virtual meeting.

Article 9: Attendance at shareholders meetings shall be calculated based on numbers of shares. The number of shares in attendance shall be calculated according to the shares indicated by the attendance book and sign-in cards handed in, and the shares checked in on the virtual meeting platform, plus the number of shares whose voting rights are exercised by correspondence or electronically.

The chairman should announce the commencement of the meeting as soon as it is due. However, if the attendees represented less than half of all outstanding shares, the meeting chairman may announce to postpone the meeting up to two times, for a period totaling no more than one hour. If the quorum is not met after two postponements and the attending shareholders still represent less than one third of the total number of issued shares, the chair shall declare the meeting adjourned.

In the event of a virtual shareholders meeting, the Company shall also declare the meeting adjourned at the virtual meeting platform. If the quorum is not met after two postponements as referred to in the preceding paragraph, but the attending shareholders represent one third or more of the total number of issued shares, a tentative resolution may be adopted pursuant to Article 175, paragraph 1 of the Company Act; all shareholders shall be notified of the tentative resolution and another shareholders meeting shall be convened within one month. In the event of a virtual shareholders meeting, shareholders intending to attend the meeting online shall re-register to the Company in accordance with Article 6.

When, prior to conclusion of the meeting, the attending shareholders represent a majority of the total number of issued shares, the chair may resubmit the tentative resolution for a vote by the shareholders meeting pursuant to Article 174 of the Company Act.

Article 10: If the shareholders' meeting is called by the Board of Directors, the agenda should be prescribed by the Board of Directors. Each motion should be subject to independent voting. The meeting should be conducted according to the specified agenda unless the shareholders have resolved to modify the agenda.

The provisions of the preceding paragraph apply mutatis mutandis to a shareholders meeting convened by a party with the power to convene that is not the board of directors.

The Chairman may not announce the meeting is adjourned until a resolution is reached for the two procedures (including motions) referred to above. If the Chairman has announced the meeting adjourned in violation of the procedures, the other board directors shall promptly assist the shareholders presented with a majority of balloting rights to elect a

50 -

chairman to continue the meeting in accordance with the legal procedures. The Chairman must give the proposal or the amendment and motion proposed by the shareholders an opportunity to be explained and discussed sufficiently until it is ready for balloting and then stop the discussion for balloting.

Article 11: Before speaking, an attending shareholder must specify on a speaker's slip the subject of the speech, his/her shareholder account number (or attendance card number), and account name. The order in which shareholders speak will be set by the chair.

A shareholder in attendance who has submitted a speaker's slip but does not actually speak shall be deemed to have not spoken. When the content of the speech does not correspond to the subject given on the speaker's slip, the spoken content shall prevail.

Except with the consent of the chair, a shareholder may not speak more than twice on the same proposal, and a single speech may not exceed 5 minutes. If the shareholder's speech violates the rules or exceeds the scope of the agenda item, the chair may terminate the speech.

When an attending shareholder is speaking, other shareholders may not speak or interrupt unless they have sought and obtained the consent of the chair and the shareholder that has the floor; the chair shall stop any violation.

When a juristic person shareholder appoints two or more representatives to attend a shareholders meeting, only one of the representatives so appointed may speak on the same proposal.

After an attending shareholder has spoken, the chair may respond in person or direct relevant personnel to respond.

Where a virtual shareholders meeting is convened, shareholders attending the virtual meeting online may raise questions in writing at the virtual meeting platform from the chair declaring the meeting open until the chair declaring the meeting adjourned. No more than two questions for the same proposal may be raised. Each question shall contain no more than 200 words. The regulations in paragraphs 1 to 5 do not apply.

As long as questions so raised in accordance with the preceding paragraph are not in violation of the regulations or beyond the scope of a proposal, it is advisable the questions be disclosed to the public at the virtual meeting platform.

Article 12: Voting at a shareholders meeting shall be calculated based the number of shares.

With respect to resolutions of shareholders meetings, the number of shares held by a shareholder with no voting rights shall not be calculated as part of the total number of issued shares. When a shareholder is an interested party in relation to an agenda item, and there is the likelihood that such a relationship would prejudice the interests of the Company, that shareholder may not vote on that item, and may not exercise voting rights as proxy for any other shareholder.

51 -

The shareholding of the shareholders without balloting right referred to above is not included in the balloting rights of the shareholders presented. With the exception of a trust enterprise or a shareholder services agent approved by the competent securities authority, when one person is concurrently appointed as proxy by two or more shareholders, the voting rights represented by that proxy may not exceed three percent of the voting rights represented by the total number of issued shares. If that percentage is exceeded, the voting rights in excess of that percentage shall not be included in the calculation.

Article 13: Shareholders are entitled to one balloting right per share except for those restricted without any voting right granted or those without any voting according to Article 179 Paragraph 2 of the Company Act.

When the Company holds a shareholder meeting, it shall adopt exercise of voting rights by electronic means and may adopt exercise of voting rights by correspondence. When voting rights are exercised by correspondence or electronic means, the method of exercise shall be specified in the shareholders meeting notice. A shareholder exercising voting rights by correspondence or electronic means will be deemed to have attended the meeting in person, but to have waived his/her rights with respect to the extraordinary motions and amendments to original proposals of that meeting; it is therefore advisable that the Company avoid the submission of extraordinary motions and amendments to original proposals.

A shareholder intending to exercise voting rights by correspondence or electronic means under the preceding paragraph shall deliver a written declaration of intent to the Company before two days before the date of the shareholders meeting. When duplicate declarations of intent are delivered, the one received earliest shall prevail, except for a declaration to revoke a prior expression of intent.

After a shareholder has exercised voting rights by correspondence or electronic means, in the event the shareholder intends to attend the shareholders meeting in person or online, a written declaration of intent to retract the voting rights already exercised under the preceding paragraph shall be made known to the Company, by the same means by which the voting rights were exercised, at least before two business days before the date of the shareholders meeting. If the notice of retraction is submitted after that time, the voting rights already exercised by correspondence or electronic means shall prevail. When a shareholder has exercised voting rights both by correspondence or electronic means and by appointing a proxy to attend a shareholders meeting, the voting rights exercised by the proxy in the meeting shall prevail.

Except as otherwise provided in the Company Act and in the Company's articles of incorporation, the passage of a proposal shall require an affirmative vote of a majority of the voting rights represented by the attending shareholders.

During the voting process, the chair or a designee should announce the

52 -

total votes represented by the shareholders present at the meeting. Each motion should be voted on by the shareholders independently. The results, agreeing or disagreeing and waived votes, should be published on the Market Observation Post System after the shareholders' meeting on the same day.

When there is an amendment or an alternative to a proposal, the chair shall present the amended or alternative proposal together with the original proposal and decide the order in which they will be put to a vote. When any one among them is passed, the other proposals will then be deemed rejected, and no further voting shall be required.

Vote monitoring and counting personnel for the voting on a proposal shall be appointed by the chair, provided that all monitoring personnel shall be shareholders of the Company.

Vote counting for shareholders meeting proposals or elections shall be conducted in public at the place of the shareholders meeting. Immediately after vote counting has been completed, the results of the voting, including the statistical tallies of the numbers of votes, shall be announced on-site at the meeting, and a record made of the vote.

When the Company convenes a virtual shareholders meeting, after the chair declares the meeting open, shareholders attending the meeting online shall cast votes on proposals and elections on the virtual meeting platform before the chair announces the voting session ends or will be deemed abstained from voting.

In the event of a virtual shareholders meeting, votes shall be counted at once after the chair announces the voting session ends, and results of votes and elections shall be announced immediately.

When the Company convenes a hybrid shareholders meeting, if shareholders who have registered to attend the meeting online in accordance with Article 6 decide to attend the physical shareholders meeting in person, they shall revoke their registration two days before the shareholders meeting in the same manner as they registered. If their registration is not revoked within the time limit, they may only attend the shareholders meeting online.

When shareholders exercise voting rights by correspondence or electronic means, unless they have withdrawn the declaration of intent and attended the shareholders meeting online, except for extraordinary motions, they will not exercise voting rights on the original proposals or make any amendments to the original proposals or exercise voting rights on amendments to the original proposal.

Article 14: The election of directors in the shareholders' meeting must be processed in accordance with the Company's election procedures and the election result must be announced immediately, including the list of the elected directors and the election weights.

The ballots for the election referred to in the preceding paragraph shall be sealed with the signatures of the monitoring personnel and kept in proper

53 -

custody for at least one year. If, however, a shareholder files a lawsuit pursuant to Article 189 of the Company Act, the ballots shall be retained until the conclusion of the litigation.

Article 15: Matters relating to the resolutions of a shareholders meeting shall be recorded in the meeting minutes. The meeting minutes shall be signed or sealed by the chair of the meeting and a copy distributed to each shareholder within 20 days after the conclusion of the meeting. The meeting minutes may be produced and distributed in electronic form.

The Company may distribute the meeting minutes of the preceding paragraph by means of a public announcement made through the MOPS.

The minutes must detail the date and venue of the meeting, the meeting chairman's name, the method of resolution, and the summary and the results of the voting (including the statistical tallies of the numbers of votes) of meeting agendas. These minutes must be retained indefinitely.

Where a virtual shareholders meeting is convened, in addition to the particulars to be included in the meeting minutes as described in the preceding paragraph, the start time and end time of the shareholders meeting, how the meeting is convened, the chair's and secretary's name, and actions to be taken in the event of disruption to the virtual meeting platform or participation in the meeting online due to natural disasters, accidents or other force majeure events, and how issues are dealt with shall also be included in the minutes.

Article 16: On the day of a shareholders meeting, the Company shall compile in the prescribed format a statistical statement of the number of shares obtained by solicitors through solicitation, the number of shares represented by proxies and the number of shares represented by shareholders attending the meeting by correspondence or electronic means, and shall make an express disclosure of the same at the place of the shareholders meeting. In the event a virtual shareholders meeting, the Company shall upload the above meeting materials to the virtual meeting platform at least 30 minutes before the meeting starts, and keep this information disclosed until the end of the meeting.

During the Company's virtual shareholders meeting, when the meeting is called to order, the total number of shares represented at the meeting shall be disclosed on the virtual meeting platform. The same shall apply whenever the total number of shares represented at the meeting and a new tally of votes is released during the meeting.
